CULTIVATO R.

SPECIFICATION forming part of Letters Patent No. 307,048, dated October21, 1884.

Application filed April 22, 1884.

To to whom it may concern Be it known that I, JOHN XV. HUDSON, a citizenof the United States, residing at \Vellington, in the county of Iroquoisand State of Illinois, haveinvented certain new and useful Improvementsin Cultivators; andI do declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings, and to the letters and figuresof reference marked thereon, which form a part of this specification.

My invention relates to cultivators of the class known as Gophercultivators, and has for its object the provision of an implescrapersmay be adjusted nearer to or farther from each other and at differentangles with respect to a horizontal plane.

The invention has, further, for its object the provision of a cutter orscraper blade, the opposite ends of which are of different widths,whereby said cutter is adapted to' be turned end for end to suitdifferent kinds of plants.

To the accomplishment of the above the invention consists in theconstruction and arrangement of parts, substantially as hereinafter morefully set forth, and pointed out in the claims.

In the drawings, which form a part of this specification, Figure l is atop plan view of my improved cultivator. Fig. 2 is a side elevationthereof. Fig. 3 is a front elevation of one of the standards and itsattached scraperblades. Figs. l and 5 are views of opposite sides of thefoot of the standard, and show the manner in which the scraper-bladesare attached to and adjusted upon the standards. Fig. 6 is amodification of the view shown in Fig. 5. Fig. 7 is a detail view of oneof the tional view taken on the line 00 m of Fig. 7.

Referring to the drawings, in which like letters of reference indicatelike parts, A designates the pole or tongue of the cultivator, pro-'vided at its rear end with a cross bar or tiinber, B, the ends of whichare equidistant from the pole or tongue.

0 designates a short transverse-timber, se-

upon the upper surface thereof, are secured (No model.)

the ends of handles 0, that extend rearward inclining to one side, andare secured to the crossbar B. The bar B is at each end and upon theforward side thereof provided with a short curved portion, 2;, fittedwith a curved plate, E, secured thereto, provided with corrugations c,with which engage similar corrugations, f, formed upon the rear surfaceof the shoes F, having flanges f, between which is secured the upper endof standard G by bolts 9, that pass through said standards and shoe, andinto and through a slot, 1), formed in the end of the bar. The bolts 9are provided with screw-threaded rear ends, and are held in position bynuts 9. G designates the standards secured to the bars, as described,and extending thence downward and forward, as shown. The standards arefirmly held by braces H, se-

cured at their lower ends by bolts h to saidstandards, and attheir upperends to the tongue by a bolt, h. Lateral movement or adjustment of thestandards G is effected by means of rods I, the lower ends of which aresecured to the bolts h of the braces H, and thence extend upwardly andinwardly to the bar B, at which point they bear against platest,.provided with corrugated upper surfaces, 2', that engage with similarcorrugations, j, upon the lower surfaces of plates J, secured to the barB by screws 9" or otherwise. The rods I are held in position by bolts jthat pass downward through slots 1) in the eross-tin1ber B, andcorresponding slots in the plates J, and thence into and through theheads of the rods I, where they are provided with nuts j". By thisdescribed construction it will be seen that the foot of either standardmay be moved nearer to or farther from the middle of the machine, forthe accommodation of narrow or wide hills or rows of grain.

K designates cutter or scraper blades, secured by braceirons k k to thelower ends of the standards G. The blades are preferably made tapering,as shown in Fig. 7, for a purpose hereinafter described. L k designatebrace-irons secured at their lower ends to the blades K, and extendingthence to the foot of each standard. The outside braces, k, arefulcrumed at is", Fig. at, upon bolts that pass through the foot of eachstandard. The inner braces, 79, are provided with slot-s k, throughwhiehthe bolts It pass. The innerfaee of each of the inside braces, 7.2, isprovided with corrugations 7.1", that engage with similar corru gations,7., formed upon a washer, 7. held in position by a nut, 75%, upon thebolt 7.. By raising or lowering the braces 7; the inner or rear end ofeach of the blades K will be raised or lowered, as will be readilyunderstood. From the bolt 76 the braces 7.: 7." extend upward for ashort distance, and are provided near their upper ends with apertures7;", through which wooden pins 7J1 pass. lhe pins 73 pass through anydesired one of a series of apertures formed in the standard, and alsothrough corresponding apertures, 70, formed in loops or straps 7., thatare secured at their centers to the rear surface of the standards.

I11 practice, when large obstructions are struck by the blades andstrain is thereby brought upon the pins 7. they will break, and thusallow the blade to pass under the standard and avoid breaking thecultivator.

In Fig. 6 of the drawingsIshowa modified form of the loops 7., in whichlinks 7; are secured to the tops of the brace-irons, said links beingprovided with apertures 73 and wooden pins 7. The blades K differ inwidth at their ends, in order that plants having different degrees ofgrowth may have the earth raised to a proper height about them, whichwill be the case when said blades are transposed or changed from oneside to the other, in viewof which the bolts that secure the brace-irons7.: 7.: to the blades are removable.

Ii designates a horizontal double-tree or evener, fulcrumed to the topof the tongue at 7, each end of the evener being attached by a rod, 7,to the upper ends of vertical doubletrees M, fulcrumed between the outerends of straps m, extending from the standards.

From the foregoing description it will be seen that a cultivator madeinaccordance with my invention is easily and readily adjusted, strong, anddurable.

I am aware that modifications in detail in construction may be madewithout departing from the spirit or sacrificing the advantages of theinvention, and I therefore claim the right tomake such changes as fairlyfall within the scope or limit of my invention.

hat I claim as my invention, and desire to secure by Letters Patent ofthe United States, is'

1. In a cultivator, the combination of a scraper-blade having ends ofunequal widths, in combination with standards and means, substantiallyas described, for adjusting such blades and standards, substantially asdescribed, and lor the purpose set forth.

2. In a cultivator, standards G, provided at their lower ends withadjustable blades K, the ends thereof being of unequal width, incombination with the pole A, bar B, plates E 0, shoes Fff, bolts 9, androds I, whereby both the upper and lower ends of the standards can beadjusted nearer to orfurther from the middle of the machine,substantially as shown and described.

3. I11 a cultivator, the pole A, connected at its rear end with atransverse bar, 13, having longitudinal and vertical slots formedtherein, in combination with standards G, provided at their lower endswith cutter or scraper blades, the corrugated, slotted, and curvedbraces 7.: 7.:, and means for securing said braces to the standards, asand for the purpose set forth.

4. In a cultivator, the combination of the pole A, cross-bar B, havingslots Z)" If, and re eessed portions 1), provided with curved andcorrugated plate E, with standards G, provided at their lower ends withadjustable scraper-blades K, substantially as described.
